At 4&5/8" by 1&5/16"--3/8" max thickness, this is a pretty decent sized Benton. Written on the one side is Lawrence County--Tennessee is where much of this collection was gathered, but the writing of the state name is not legible--as the close-up shows. Being a Ft. Payne chert that part of western Tennessee would be exactly right. Being a Mid Archaic piece there is dulling on the sides of the stem but not on the basal edge--basal grinding simply wasn't their way of making their large knives. The piece has been in a local doctors' collection for decades, no other provenance with his passing. Patina is "no-brainer', every detail is lifetime guaranteed authentic, Shipping is $5.00 due to the weight, and checks or M.O.s are welcomed, day-after-receipt shipping on either one--Roy A.
